SPECIFICATION forming part Of Letters Patent N0. 744,757, datedN'oveifnloe` 24,1903.

Application led June 10, 1903. Serial No. 160,942. (No model.)

To cir/ZZ whom it may concern:

Be it known that I, FRANK HERBECK, a subject of the Emperor ofAustria-Hungary, residing at Orange, county of Franklin, Commonwealthof-Massachusetts, have invented new and useful Improvements in Floor-Planers, of which the following is a specification.

This invention relates to door-planing machines, and particularly tothat class in which a rotary head is used to carry cutters,scrapers, orpolishers.

The great difficulty in successfully planing oors with most machinesarises from their inability to adapt., themselves to the surfaceconditions of the floors in which boards have become sprung or warped orwherethe floor has settled Vin parts.

It is the object of the present invention, therefore, to provide amachine which will follow the general irregularities of the fioor whilesmoothing the surface roughness and which will provide' various othernew and useful features hereinafter mentioned. Y

Y'In the drawings,in which like letters of reference indicatecorresponding parts throughout, Figure 1 is a side View of the machine.Fig. 2 is a plan; Fig. 3, .a longitudinal section; Fig. 4, a top view ofthe lower sandpaperblock; Fig. 5, a view of the block partiallyassembled; Fig. 6, a view of the scraper, and

Fig. 7 a view of a plane member. Fig. Sis a detail View of the slitclamp, showing the conical neck S.

A is a frame mounted upon the axle B of the wheels O, which positivelyturn the same by pawl-and-ratchet'connections when the machine is rolledforward by a handle D, which is removably connected at b. axle B carriesa beveled gear E, which meshes with a'gear F on Athe rear end of theshaft Gr, which is in turn geared at its forward end to the rotary headH by gears I and J. This head H and its gear J arecarried in abracket Kon the frame and are free to rotate therein.

L is acollar fast on the head H, and to it are pivoted arms M, whichcarry pivoted to their outer ends the tools, the same being pressed intoworking engagement with the oor by the spring N, adjustable through thescrews n.

P is a segmental plane having a slot p in The ` its side through whichthe arms Mwork.

This plane is flat throughout most of its length; but vits face risesslightly at its for- -ward end to ride over irregularities in the floor.

S is a scraper-blade held in a forked clamp- S,which is slit andslightly conical at its neck s, so that it is compressed as it is drawnthrough the opening in the block S2.

SE is a slot in which the arms M are pivoted by the bolt end s of theclamp S. A thumb-nut Y holds .the scraper tight and the block on thearm.

In addition to the plane and scraper above described a sandpaper-block'is furnished, which consists of upper and lower blocks U U side with arubber pad Z to cushion it in its work, and on its upper face projectbradpoints u, on which the paper is pressed to hold it in place whilethe upper block U is put in position. This upper block U has an openingin its middle to receive a perforated stud W, which is Vmounted on thetop of the lower block andwhich by means of a key Y acts to force theupper block down upon it. The key V has a cam-shaped projection o',which is greater in breadth than in height, and as this is insertediiatwise in the slot w of the, stud W and turned edgewise by its Thelower block is faced on its lower v lever U2 it forces the topblock'down upon the Y lower block and'cla'mps the ends of the sandlpaper bent thereover. f. The upper block also carries on its upper faceears Y and a thumbscrew Y2 for attachment to the arms of the machine.

All of these tools are readily removable by thumb-nuts and can besubstituted one for another in afew minutes. The machine may also beeasily dismantled, so that it can be packed in an ordinary carpenterschest.

A rubber-faced buer-rail X (shown in Fig. l) is thrown out around themachine to prevent its striking. and damaging baseboards or walls. y

The head H is supported by a swiveled caster Y, which allows themachine'to be turned and pushed in any direction, while thespring-pressed arms hold the planes or other tools to the door with afirm steady pressure.` l The number course be increased and the partsvariously modified Without departing from the spirit of my invention.

What I therefore claim, and desire to secure by Letters Patent, is

1. In a hoor-planing machine, a rotary head, pivoted arms upon said headcarrying tools, and springs for holding said tools in contact with thedoor.

2. In a floor planing machine having Wheels, a rotary head, pivoted armsupon said head carrying tools, springs for holding said tools in contactwith the floor and means for rotating the head from said Wheels.

3. In a door-planing machine mounted upon wheels, a rotary head, meansto rotate said head from said Wheels, pivoted arms upon said head, toolsconnected With said arms, springs for holding said tools in contact withthe floor and a swiveied caster for supporting said head.

4. In a Hoor-planing machine the combination of the rotary head, meansto drive said head, arms pivoted thereto, a spring bearing upon saidarms and adjusting means for increasing the pressure of the springthereon.

5. In a fioor planing machine, a rotary head, an arm pivoted thereto,said arm carrying a plane having the forward end of its face rounded up,and springs for holding said plane in contact with the floor.

In testimony whereof I aiix my signature in presence of two witnesses.

FRANK I'IERBECK.
